Application led October 24. 1818. Serial No. 259,600.

To all whom it may concern.'

Be it known that I, a citizen of the United States, resident of Louisville, in the county of Je erson and State of Kentucky, have made a certain new and useful Invention in Gusolene-Dispensing Apparatus; and I declare the following to be a full, clear, und exact description of the same, such as will enable others skilled in the nrt to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a central vertical section of the invention, with partsin full lines, and showing an electric pump.

Fig. 2 is a side view o the dispenser, the casing thereof being sectioned, and parts being broken awa F Fig. 3 is a detail section on the line 3 3,

igig. 4 is a detail sectional view of one of the check valves. l

Fig. 5 is a detail perspective view of the upper part of the dispenser casing showing e for the receiving vessel. as relation to instruments asolene, having iable means for The invention for dispensing liquids, as for an object to provide re ascertaining deiinitely the amount of oil dehvered by the wholesaler to the dealer or garage owner, and the amount delivered b Y the dealer to customers. Another object 1s to avoid waste of gasolene through careless handling of the same, and to avoid ernors or peculations or fraudulent deliveries, .Y thereby conserving the gasolene suppl .Another object is to provide indisputabl means for assuring both the customer and the dealer that each has received a full and dand paid or.`

In the gasolene dispensers now used, it is recognized that there is no propelmeans for avoiding errors or eculations, which are taking place with a arming frequenc and totaling very considerable losses, this being due to the fact that either the dispensors do not register, or if they 'ster the registration is inaccurate, and t at there is no means for checki up on the re istration, to ascertain if it 1s correct.

gdhe invention consists in the novel conparts, coming the claims as hereafter p e 6, extending above the level of tank 2 and movable vertically through the change of level of the liquid contents of the tank, a stationair Vmarker 7 showing upon the movable scae thevcontents of the tank in gallons.

gasolene dispenser 8 is locatedk suitably to serve customers, and may be either adjacent to the supply tank or s aeed apart therefrom by a considerable istance, according to the special conditions or requirements.

This dispenser is provided with a receiving 10. Between the two a conduit for delivery of the liquid from the sup ly to the receiving tank. As illustrated t is conduit includes a i e 11, opening into the bottom portion optli tank and communicating with the su plv tank near the bottom of the latter, a clieck valve 14 bein disposed at the lower end of the pipe 11` eneath the level pf the liquid in the supply tank.

furnis gasolene to the line 11, being as show n'an electrically operated centrifugal pump, the closing and op in? of an electric circuit by the ressue-and re ease of a push button switc serving to set the pump into and out of action to start and stop the supply of liquid. The li uid is by a filter cloth or mesh the pump is primed and a delivery effected;

e receiving vessel. once The receivin tank 9, which also serves as a dispenser tan is provided with means to indicate, the amount of li uid therein. In the presentl embodiment means comprises a-vertical gage glass 19, communicatlng at-,its upper and lower ends with the 1nterior of the tank and showing at all times the amount of liquid delivered to the tank from the Sup ly tank by the operation of 41l) the pump. d) scale 'adjacent to the gage glass is graduated to show in gallons and Afractions,thereof the contents of the receiving tank, said scale being preferably double and including a scale 20, at one site of the glass, reading upwardly, and a scale 21, at

thev other side of the glass, reading down` wardly. It is preferred that `the receiving tank shall have delivered thereto for each sale or ,transaction a definite, predetermined uantity `of gasolcne, as, for instance, 10 ga lons, 'andto enable 4this tohe donc, an overfiow conduit' or pipe 22 `communicates with the `supply tank and returns to the latter any liquid delivered -to the receiving tank above a certainheight, being the ten gallon line, said overflow pipe communicating with a drain pi ed'f leading from a: dispensing port Vin 'it e bttoni of the measuring vessel. l,s0 A three-'way valve 24 to contrer dispensingis'iinterpdsed in the drain pipe 23 at a suitable lieiglit'for convenient operation by the dealer, and a delivery hose 24 has connection 'with this valve, whereby, upon opera'tioni'ofV the "valve, the contents of the receiving' tank 9V or any portion thereof can be rurr into the container of the automobile, and uponfnrther operation of the valve any remainder of gasolene in the tank 9 may be 40 gravitated back to the supply tank 2. It livvill be perceived that the receiving tank 'may lie drained into the supply tank at will, by operation of valve 24.

' Toplainly show in which direction the gasolene'is passing from the measuring vessel, enuindicator 25 is fast upon the handle of `the three-Way valve, and has marked `thereon the sign To you or To auto for oneposition of the handle, and Back to tank and Oil for thc other positions of `the handle.

The dispenser casing is provided with an inclined support or rest Q6 for a tablet, to be used in taking the readings of the measuring vessels scale' for each sale.

The pnlnp may be primed by removing the cap' 27 of an upper opening of the lter 'easing '17andipouring gasolene therein. In

starting'theopeiat-ion of the apparatus, the puin is 'set "in action by pressure of .the push button switch, gasolene being delivered ithioulghtliehpipc 11 into the measuring vessel,` t ,the ten gallon line, the push button *beinggthen released to stop the pump. The

mifihpse'bemg then inserted into the auto container, the three-Way valve is operated and the required amount of gasolene delivered to the auto, after which the threeway valve is further operated to either drain back any excess into the supply'tank or merely to stop the delivery to the automobile. f

The three-Way valve 24 enables the operator to dispense liquid from the receiving tank through the pipe 23 and simultaneously cut ofi' flow from pipe 23 to the overiow pipe, a part of which latter pipe operates to drain when the valve 24 is properl set. Thus, when dispensing is being e ected, communication between the dispensing port in the bottom of the receiving tank and the overiow pipe' is closed, and when the valve is closed against dispensing said communication may be either closed or open, depending on the position of the. valve. Y t will be erceived that by the construction describe ositive assurance of the disensing of pre etcrmined amounts of liquid is effected with a high degree of accuracy. The check valve 14 retains a constant 90 amount of liquid in the intermediate conduit 11 between dispensing operations from the receiving tank, so that the indicators on the two tanks are checks on each other. These indicators are responsive to change of liquid level in the respective tanks, and in normal dispensing operations discharge from the supply tank is not only indicated by the indicator for that tank, but is also accurately indicated by the indicator of the receiving tank. This is believed to be due in eat measure to the fact that the quantity o liquid in the intermediate conduit is a constant factor relative to eaclr indicator, and that this constant factor is maintained, once the linstrument has been operated.

I claim:

In a dispensing instrument for liquids, in combination, a sup ly tank, a receiving tank, a conduit for de ivery of liquid from the supply to the receiving tank, means for each tank adapted to indicate the amounts of liquid' thereinrespectively, means whereby a constant amount of liquidis retained in said conduit between dispensing operations from said receiving tank, andA an overliow conduit for said receiving tank communieating with said supply tank.
